习惯用C#写东西,但平时又会碰到很多要用win32 API的地方,所以经常要用DllImport,但win32函数的类型写法是很庞杂的,相信为之困扰的不止我一个,现在我整理一份我个人的理解如下,希望高人不吝赐教。
我的基本原则有如下几点:
1、下面都是针对32位系统的，所以int是32位.long也是32位；
2、各种句柄类的(H开头)，我认为一律是System.IntPtr，到目前为止没发现出错；如果哪位在使用中出错，请指出；
3、LP和P，我实在不懂(对C 不太了解)，对于LP和P开头的函数，如果是和STR有关的，一律写为System.String，像PLCID这样指向什么东西的，写为System.UInt32(因为指向另一个地址，那就是指针，指针是32位吧)，int之类的数值型，那我就写为int[]，以方便.net程序引用(写成System.UInt32的话，给API调用应该也不会出错，但.net程序就不好引用了)

如有意见，欢迎指教。谢谢
